  3. Writing the ISO to a USB Drive:
    • Using dd (Linux/macOS): Open a terminal and use the dd command. Be extremely careful to identify the correct USB device name (e.g., /dev/sdX where X is the drive letter, not a partition like /dev/sdX1). Running lsblk can help identify your USB drive.
      sudo dd bs=4M if=/path/to/archlinux-xxxx.xx.xx-x86_64.iso of=/dev/sdX status=progress oflag=sync
      Replace /path/to/archlinux-xxxx.xx.xx-x86_64.iso with the actual path to your ISO file and /dev/sdX with your USB device.
    • Using Rufus (Windows): Rufus is a popular and user-friendly tool for creating bootable USB drives on Windows. Select the ISO, your USB drive, and ensure the correct partition scheme (GPT for UEFI systems) and target system are selected.
  4. UEFI Compatibility: When creating the USB, ensure it’s formatted for UEFI compatibility. Most modern tools will handle this automatically when selecting a GPT partition scheme.

Configuring BIOS/UEFI Settings

Accessing the Zenbook’s BIOS/UEFI is typically done by pressing a specific key (often F2 or DEL) during startup.

  1. Boot Order: Prioritize the USB drive in the boot order. Locate the “Boot” or “Boot Priority” section and move the USB drive to the top.
  2. UEFI Mode: Ensure the system is set to UEFI mode rather than Legacy BIOS. This is critical for booting the modern Arch Linux installer.
  3. Secure Boot: If Secure Boot is enabled, it might prevent the Arch Linux ISO from booting. It is generally advisable to disable Secure Boot for the installation process. You can potentially re-enable it later if desired, though it can add complexity.
  4. Fast Boot: Some BIOS settings include “Fast Boot” or similar options. Disabling these can sometimes help ensure that all hardware components are properly initialized during the boot process.
  5. Save and Exit: After making these changes, save your settings and exit the BIOS/UEFI.
